Recent Global Comments Widget stopped working

I have the Recent Global Comments Widget (and comment-indexer) and the Recent Global Posts Widget (and post-indexer) installed and from start they both worked. Have done the “sql.txt” code and it was all good.

How ever, after some days the RG Comments Widget stopped updating and has been “inactvie” for about a week. (The Post widgets is still running smoothly).

Any suggetsion to what the problem can be? Have I missed something?
